Yesterday, tennis star Serena Williams tweeted a risque photo of herself, clad in a bra and panties behind a sheer curtain. Williams' curvy silhouette caused a stir around the web, with many calling the photo a bad move, especially on the heels of her stalker scare just last week.

Some say the sultry photo is suggestive of someone "peeping" on the tennis champ. Williams removed it from her Twitter page, but several copies of it have been floating around on the web.

Williams' stalker was arrested when he was found wandering around on her property carrying love letters he had written to her.
